Análisis multi-temporal de cobertura vegetal en la zona sur de Ecuador (Provincia de Loja)

Abstract

Abstract:The present curricular integration work shows a multi-temporal analysis in the southern of Ecuador, province of Loja, between the years 1991 to 2020 from satellite images obtained from the Landsat and Sentinel 2A. Thus, it was possible to identify and quantify the vegetation cover in the given periods and establish rates of change. The land cover classes in the study area were established taking into account the classification established by the MAE. A supervised classification was used using the free access software QGISfor satellite image processing, using the Semi-Automatic Classification (SCP)plugin, applying the Minimum Distance method to obtain results. The main results show a reduction in forests in the period 1991 -2001 and an increase from that period, it is also possible to show a gradual increase in the anthropic zone due to population growth. Finally, it is possible to establish a baseline to quantify the vegetation cover and to be able to establish rates of change.
